So some pants that I just bought a few weeks back are tight already

I haven't weighed myself in that last two weeks, I am kind of afraid to do that...
Heres the plan:
The nieces and nephew start school on the 13th I plan to go walk/jog every morning after I put them on the bus. I don't know if I will go back to following WW or not yet, but we'll see.. I can't really afford to pay for it anymore, but I guess I can just follow it from what I know already since I have the books and all!!! The plan is to be 115lbs before I TTC in May/June... I'll start loggin my food and all on the 13th, well crap I can't I just remembered we leave on the 14th for a mini vacation

Ok well now the plan is to start loggin my food and all again on the 18th!!! Ok wish me luck!!!!
